  "details" : [ "libdwarf 0.4.1 has a double free in _dwarf_exec_frame_instr in dwarf_frame.c.", "A double-free vulnerability was found in libdwarf's dwarf_expand_frame_instructions() function of the dwarf_frame.c file. A carefully crafted object file could cause the ‘dwarfdump' utility to do a double free in handling an error condition. This issue could cause a segmentation violation or other major error, terminating the calling application and resulting in a denial of service." ],
  "statement" : "The vulnerable code was introduced upstream in libdwarf-0.3.0, and later, Red Hat ships lower versions of libdwarf, which do not contain the vulnerable code. Hence, versions of libdwarf shipped with Red Hat Enterprise Linux 7 & 8 are not affected by this CVE.",
